Application flledil'uly 14, 1923@ Serial No.-651581.

To @ZZ whom' t may'v concern:

Be it known thatfl, TiLLIAivrrKoLLER-,Ya

citizen of the United State's,'residing at Pomeroy, in the 'county fof Garfield andState -ot iV'ashington; have invented certain .new andL useful Improvements '-in a VVee'dlng iMa chine; and I do hereby declare thelifoll'owe' ing to be'a fullfclear, 'and exact 'description oftheinvention, such as will enable"( )ther's4V 7'skilledin theart towhichit; appertain's `'to make Vand 'usev the samei.y

This Linventi'onrelatesfto' a weeding ma-l chine@v y y lt is aimed vto provide a novel construction 1 of machine Y- adaptedto more expeditiouslyV and eiiiciently" cut"'th`e l'weeds and particularly one having a rotatable# cutter provided vwithV one or more helical cutting ect isto'rpinvide a constructtion'i'n which the said cutter lmaybe'ifo'rmed by the twisting offa rod" or'bar.

Itis further aimed to provide a novelV construction of (machine. adapted tojcarry the cutter, to permit efficientadjustment and variation in theposition thereof and with a view to driving thecutter through the move# mentof the ground wheels 'of the 'machine'or implement.Y

Additional objects and 'advantages ywill become'apparent from'a consideration of the description following taken inconnection with accompanying drawings 'fill'ust'ratlng an operative embodiment/.f

1n said dra-wings:-

Figure 1 is a plan view of the machine;

Figure 2 is a front elevation thereof;

Figure 3 is an end elevation of the machine with one of the wheels removed,

Figure 4 is a cross sectional view of the line 4-4 of Figure 1, and

Figure 5 is a detail sectional view illustrating the pawl and ratchet connection between the wheels and axle of the machines Like reference characters designate like or similar parts in the dierent views.

In reducing the invention to practice, a substantially rectangular frame is provided as at A having end beams at 10 and horizontal beams 11. Depending from the end beams 10 are bearings or hangers 12in which a shaft or axle 13 is journaled. Ground wheels 14 are fastened to the axle 13 in such a manner that when the machine moves forward the axle will turn with such wheels but should the machine be backed, the wheels will rotate independen'tlyof the axleysuch result .beingbrou'ght about-by 1a lpawl andl ratchetandhub and shaft -connection of usual or approved form.

Frame A is provided withfan .intermediate f horizontal beam-atfl and, at suitable spaced* w yintervals along tliesam'e,-risers or blocks 16v are secured. 1

Asupporting beaml? :for the cutter to bez: llater described 'extends 'substantially paral-A l lel; with' the beams x11-.fand f 15 'and is hinged on Yhorizontal:axes as at Y18 to the-` risers orbloc-ks 16, The position ofi-beam :17 may? bel varied throughv the manipulation yof an. (arm 'or llever .'19 having. ,divergent 'straps 2O :,se-V cured to theupper andy lower surfaces ofbeam V17 and movable relatively'to and adaptedto lbexlocked to a plate or' segment 21.. This plate or'segmentllis1fastene'd-'at one'end to one beam .11 and at itsvother or upperendv to a post 22.'.-which .rises ffromi th'elframe A; and:A is bracedby `meanswof a diagonalrodH as at 23.' Pla-teQlis notched asl at 24in order "8O carried :by `lever19, selectively,V iny orderwto-` fasten such lever in different positionsfandf toreceive a locking lplunger-'forfthewlike 25 accordingly the bar f1? indifferent positions.

Substantially U-"shaped5 vhanlrers 26 are connected by horizontal -:pivots 2r. tothe beam- 17 on substantially horizontal axes', and to eye bolts 28 of one of the beams 11.' At the low--y ermostportion ofthe hangers' 26 v'are carried suitable blocks tor bearings'hQQ Ain which auf elongatednutter 30 is jeurnaled byfmeans of.-

round portions 31.

Said cutter 30 consists of a metallic rod or bar which is twisted so that it will have the portions 31, and helical ridges or cutting edges 32.

Rotary motion is imparted to the cutter 30 in any suitable manner. For instance, a gear wheel 33 may be keyed to the shaft or axle 13 and disposed in mesh with a smaller gear wheel or pinion keyed to a shaft 35 which is journaled in hangers or brackets 36 suitably fastened to andpdepending from the frame A. The shaft 35 has a ball and socket connection at 36 with a link 37 having a link 38 extensibly connected therewith for unitary turning with the same and which link 38 in universally connected as at 39 to one end of the cutter 30.

A seat 40 may be provided for the driver on the frame A and a draft tongue 41 may extend from such frame.

Hangers or brackets26 may be reinforced CII J and in proper position with respectV to the ground or weeds to be cut. The parts are locked in adjusted position through the release of the lock and its engagement with the appropriate notch 24. The movement of the bar 17 controlling the position of cutter is permitted by the hinge or pivotal connections at 18, 27 and 28. The adjustment of the cutter does not affect the driving connection thereof with the gear wheels 33 and 34 in view of the extensible or slip connection of the links 37 and 38. As the machine is drawn over the weeds, the rotation of ground wheels 14 forwardly will correspondingly rotate the axle 13 so that through the medium' of the gear wheels 33 and 34, shaft 35 is driven. The cutter is driven from shaft 35 in viewof the connection of the links 37 and 33 therewith at 36 and 39, respectively. As .the cutter 30 rotates, the cutting edges 32 are brought into engagement with the weeds in advance of the cutter so that the latter will be hewn or out from their roots relatively close to the ground'.

Changes in the details may be resorted to provided they fall within Athe spirit and scope of the invention.

Having thus described the invention,-

what I claim is:

l. A weeder having a frame, axle carried by said frame, ground` wheels to drive saidv axle, a beam extending longitudinally of .the frame, risers on said beam, a second beam, said second beam being hinged to said risers, a lpost rising from the frame, a lock member secured Vto* said post and frame, an adjusting lever leading rigidly from said secondbeam and having means for locking engagement with said lock member, substantially U-shaped hangers pivoted to the second beam and to the frame, bearings carried by said hangers adjacent their lower ends, a cutter journaled in said bearings, a gear wheel on said shaft, a. gear wheel driven by said gear wheel, and alink connection between the secondgear wheel and said cutter.

2. A weeder having a wheeled frame, said frame having a longitudinal beam, a second longitudinal beam on said frame, a beam pivoted to the second longitudinal beam and dis-posed on the side thereof opposite to the first mentioned beam, articulate hangers connected to the first mentioned beam and to the third mentioned beam, a cutter mounted by said hangers, means on the frame to Vadjust the third mentionedl beam to vary the position of the cutter 0011-. sisting of a post rising from the frame, a locking plate connected to the post and to the frame, an adjusting lever rigidly connected to the third mentioned beam andhaving latch means associated with said locking plate, and a brace extending from the post on the opposite side thereof to the locking plate and across the second and third mentioned beams and fastened to the first mentioned beam.

In testimony whereof 'I afIiX my signa# ture in presenceof two witnesses.

WILLIAM KOLLER.
